[0002] Gels refer to thick liquid or semisolid preparations made of drugs and excipients that can form gels, such as solutions, suspensions or emulsions. Usually, gels are limited to local use on the skin and body cavities (such as the nasal cavity, vagina and rectum). Emulsion gels are also called latexes. Gels made from polymer matrices (such as tragacanth gum, etc.) can also be called slurries. Gels formed by small particles of small molecule inorganic drugs (such as aluminum hydroxide) existing in a network structure in a liquid are two-phase dispersion systems, also known as suspension gels. Suspension gels can be thixotropic, semisolid when still and liquid when stirred or shaken.

[0003] The preparation steps include selection of raw materials, mixing, reaction, filtering and drying.

[0004] The reaction in the reactor is to react the mixed raw materials in a closed reactor, and control the temperature and pressure of the reaction by heating or pressurizing to accelerate the reaction process.

[0005] The conventional method of controlling the temperature and pressure of the reaction is to heat the outside of the reactor. Direct heating of the reactor requires high energy consumption, and after the reaction, it is not convenient to effectively recycle the heat. In addition, gelling agents are easily attached to the inside of the reactor, which makes it difficult to fully discharge the product. Utility Model Content

[0011] The booster fan delivers air into the reactor through an air intake pipe, and an air intake valve is provided on the air intake pipe;

[0012] A temperature sensor and a pressure sensor are also arranged in the reactor.

[0013] Furthermore, a feed pipe for introducing mixed raw materials is arranged at the top of the reactor, and a drain pipe for draining liquid is arranged at the bottom, and both the feed pipe and the drain pipe are provided with solenoid valves.

[0014] Furthermore, the agitator includes a stirring shaft installed in the reactor, stirring blades arranged on the stirring shaft, and a crescent scraper arranged on the stirring shaft and in contact with the bottom of the reactor; wherein the top end of the stirring shaft is driven to rotate by a reducer and a motor.
